MFSEXITF= parameter for procedures

Use the MFSEXITF=field-exitnum parameter in procedure to specify the highest-numbered MFS Field Edit exit routine to be loaded by IMS.

field-exitnum must be a decimal number greater than or equal to 0. It must also be less than the default or specified value for the MFSEXITS=segment-exitnum keyword parameter. If MFSEXITF is not less than MFSEXITS, then IMS issues DFS1920I and sets defaults for both keywords. The default is 0.

The IMS-supplied MFS Field Edit exit routine DFSME000 is always loaded. For example, an MFSEXITF=14 specification indicates that the user-supplied MFS Field Edit exit routines DFSME001 through DFSME014, and the IMS-supplied DFSME000, are loaded by the IMS system. The user-supplied exit routines must be placed in an authorized library in the JOBLIB, STEPLIB, or LINKLIST library concatenated in front of the IMS.SDFSRESL. If any exits cannot be loaded, then IMS will issue message DFS1934E for each exit that could not be loaded.
